Other Business Cycles Theories

For comparison, I am looking into other theories of business cycles, namely Chicago and Keynesian. Does anyone off the top of their heads which works are cited as the defacto Chicago and Keynesian analysis of business cycles? Do they have something like Mises, Theory of Money and Credit, or like The Austrian Theory of the Trade Cycle compiled by Ebeling, but with respect to their theories?

Keynesians are under-consumptionists. There’s always General Theory and Khaldor’s work.
